Abstract
This chapter provides a status update as of 2018 on space tourism offerings either currently available or actively in the development process. The aim is to perform an evaluation of how the offerings respond to the aspirations described in the earlier chapters and also to provide a basis for the discussion on implications of space tourism described in subsequent chapters. In addition to analyzing suborbital, orbital, and lunar developments, the chapter discusses the state of the infrastructure supporting space tourism advances. This provides a perhaps subdued reality when compared with the heady initial hopes.

Abstract
Addresses the current state of the art of wireless technologies and infrastructures, projects where the field will be in the next decade, and discusses some of the challenges that must be met. Elaborates on the established major areas of commercial wireless access technology in the USA, ranked by deployment extent, which are: terrestrial mobile wireless access; terrestrial broadband wireless access; and mobile satellite service.

Abstract
Purpose
The purpose of this paper is to examine the potential applications of stratospheric communication platforms (SCP), which have been recently introduced as an alternative for satellite communications.
Design/methodology/approach
Various applications, solutions and services are planned by using aircraft or airship SCP, which could be classified as digital narrowband or broadband, depending on the broadband required. The platforms as base stations can provide service for fixed and mobile applications, with commercial and military solutions. Subscribers will use uplink to the platform for transmitting and receiving information, where onboard SCP switching devices will downlink to the ground station and route traffic directly to other subscribers within the same platform coverage, to another platform via optical inter‐platform links, trough heterogeneous networks including satellite or to the terrestrial telecommunications network. Each SCP can deploy an antenna for large coverage area or a multibeam antenna capable of projecting numerous spot beams within its potential coverage area.
Findings
This paper outlines the findings of fixed and mobile applications, features, testing and some specific development programs of SCP using aircraft solutions, such as SkyTower and airship solutions, such as CRL/TAO/NAL.
Research limitations/implications
Particular consideration is given to the use of SCP for delivery of future broadband, broadcast and multimedia wireless communications including research for new communication, navigation and surveillance (CNS) implications.
Practical implications
SCP will provide communication facilities that can exploit the best features for both terrestrial and satellite schemes.
Originality/value
Emerging solutions of voice, data and video over IP are offered by SCPs operating in the stratosphere at altitudes of up to 25 km.

Abstract
Purpose
This paper aims to contribute to a growing body of work (re)imagining the future for Black girls by calling Western notions of time into question. At its core, this paper argues that all Black girls are imaginative beings and that it is essential that Black girlhood imagination as a mode of future-making praxis be considered an integral component in the pursuit of Black liberation. To do such the author engages Black feminist futurity Campt (2017) and Black Quantum Futurity Phillips (2015) to illuminate ways a reconceptualization of time provides us with an analytical tool to amplify Black girls’ liberatory fantasies.
Design/methodology/approach
A literature review was conducted to synthesize Black girls’ freedom dreams (Kelley, 2002) across time in an effort to demonstrate that Black girls, despite their conditions, are experts in self-defining their dreams of the future. It also highlights methods that researchers use to elucidate the freedom dreams of Black girls years past.
Findings
This paper underscores the urgency in applying future-oriented research practices in the attempt to create a new world for Black girls. It also demonstrates that Black girls have always been and always be, imaginative beings that engaged in future-making dreaming.
Research limitations/implications
The author offers a conceptual framework for researchers committed to witnessing Black girl imaginations and in an effort to work in concert with Black girls to get them freer, faster.
Originality/value
This paper makes the argument that studying the imaginations and freedom dreams of Black girls requires the employment of future-oriented theories that have a racial, gender and age-based analysis.

Abstract
INTELSAT, the International Telecommunications Satellite Organization, was besieged by a number of major problems when the author took the helm three years ago. These problems required what was tantamount to a classic “corporate turnaround.” The turnaround has been effected; the challenge now is to sustain momentum.
